Stiffening of the lense is?

A

Presbyopia

18
Q

When you’re short sighted this is called?

A

Myopism

19

When you’re far sighted this is called?

A

Hyperopia

20
Q

Blurring images in certain directions is called?

A

astigmatism

21
Q

These are all descriptors of?
populate the macula and fovea
active in high light levels
responsible for color vision

A

Cones

22
Q

These are all descritpors of?
populate the periphery of the eye
active in low light situations
very sensitive to change and motion

A

Rods

23
Q

the ironically photoreceptive retinal ganglion cell impacts our circadian systems and seeks blue

A

3rd photoreceptor

24
Q

Rods and cones perceive color?

A

Differently

25
Q

What color do cones favor?

A

Yellow

26
Q

What color do Rods favor?

A

Green

27
Q

Vision under well-lit contiions, which provides for color perception, and which functions primarily due to cone cells in the eye

A

Photopic vision

28
Q

A combination of photopic vision and scotopic vision in low lighting, which functions due to a combination of rod and cone cells in the eye

A

Mesopic Vision

29
Q

Monochromatic vision in very low light, which functions primarily due to rod cells in the eye

A

Scotopic Vision

30
Q

_____ gives rise to the sensations of brightness

A

Illuminance

31
Q

_____ is a result of?
The intensity of light falling on a given region of the retina at a certain time
2.
The intensity of light that the retina has been subject to in the recent past (adaptation)
3.
The intensities of light falling on other regions of the retina (contrast)

A

Brightness

32
Q

Cone or Light adaptation is similar to?

A

Dark theater into daylight

33
Q

Rod or dark adaptation is similar to?

A

daylight into dark theater

34
Q

_____ _______ is an example of subjective constancy and a feature of the human color perception system which ensures that the perceived color of objects remains relatively constant under varying illumination conditions. A green apple for instance looks green to us at midday, when the main illumination is white sunlight, and also at sunset, when the main illumination is red. This helps us identify objects

A

Color Constancy

35
Q

Our learned experience of color influences the brains perception of light….tomatoes are red, grass is green, blood is teal etc.

A

Color Constancy
